Right colon

Definition
The cancer of the right colon is localised in the right part of the colon who goes from the caecum to the angle right colic.

This surgical pathology is treated with a right hemicolectomy.

It is about a resection of the right colonist, with re-establishment of digestive continuity.

It is carried out thanks to a joining (= anastomosis iléo transversee) between the distal small intestine and the transverse colonist

Risk factors

Risk factors cancer right colon

  • Polyps

  • Between 60 and 80% of cancers of the colon develop on précancéreuses benign tumours: polyps or adenomata. The frequency of these lesions increases regularly with the years. According to the observations collected at the time of autopsies, 12 % of the people of less than 55 years are reached by it.

  • age

  • Rare before 40 years, cancers of the colon

  • heredity

  • All in all, the existence of a cancer in a relative of the first degree would multiply by two the risk of cancer.

  • family forms

  • Certain family diseases involve a main risk of cancer of the colon. It is in particular the family adénomateuse polypose, which are characterized by the early appearance of multiple polyps on all the colon, and the syndrome of Lynch.

    The early development of a cancer is inescapable in the event of polypose family

    In the syndrome of Lynch, the risk is extremely high, but a little later. It is associated an increase with the frequency of cancers of the endometer like, to a lesser extent, other cancers (stomach, ovary, urinary tracts…).

  • inflammatory diseases of the intestine

  • The influence of the disease of Crohn on the cancer of colon remained discussed a long time.

    The ulcéro-hemorrhagic rectocolite is a classical risk factor of cancer colorectal. However, the risk is function of the extent of the attack colic and its seniority

    Today, it seems clear that this disease is also an important risk factor when it reaches all the colon and that it began in young age.

  • Supplies

  • Other risk factors of cancer of the colon were evoked, such as a food low in fibres and rich in grease.

In addition certain data suggest that the chronic anti-inflammatory drug catch not stéroïdiens could play a protective role. But these factors remain very discussed

Surgical treatment

 

Right Hemicolectomy

  • Operational indications

  • Cancer of the right colon: caecum, ascending colon, angle right colic

    Polyp colic not résécable by endoscopy

    Disease of Crohn reaching the iléon (small intestine terminal)

 

  • The carcinological intervention comprises a exérèse carrying the end of the last handle iléale and the colonist until one the right third of the transverse.

    It is necessary to carry out a binding first of the right vessels colics higher, colics means, and ileo-caeco-colo-Appendicularia in contact with the higher axis mesenteric.

    The re-establishment of continuity is carried out in same time with anastomosis iléo-transverse termino-final or termino-side

 

The intervention can be realized  

  • by a traditional technique

  • maybe by laparoscopy (mini invasive, closed belly)

 The operational act is longer in coelioscopy than in open surgery.

The resumption of the transit and the food is probably faster after right colectomy by laparoscopy (coelioscopy).
The duration of hospitalization is probably not very different according to the technique used.
The carcinological quality of the resection and postoperative quality of life are not different for the laparoscopy (coelioscopy) and the open surgery.
For the disease of Crohn, there exists an important benefit parietal and aesthetic related to the use of the long-term coelioscopy (young patients and iterative interventions).

Complications

 Complications after Hémicolectomie right-hand side

COMPLICATIONS

  • They are rare.

  • It is about a surgery frequently carried out.

  • The technique, either by laparoscopy, or by opened way, is standardized, sour and reliable.

The anastomotic leak is major complication after resection colic

                                     

The risk of dent is estimated between 1% and 3%. It is about a matter escape through the joining colic because the joining is not tight.

This dent can involve a post-operative peritonitis, which imposes a reintervention in urgency and sometimes the clothes industry of a double stomy on gun of rifle (artificial anus) with disassembling of anastomosis

Obstruction of the bowels

A difficult resumption of the transit can make necessary the realization a scanner to eliminate diagnoses it postoperative obstruction of the bowels on support or internal hernia (imprisonment of a handle of hail in a breach created by the intervention).

L’abcès of walls is rare after laparoscopic surgery

 

Other risks are inherent in any act of abdominal surgery: 1) iatrogenic attack/wound of another abdominal body 2) haemorrhage…

Anticoagulants are prescribed to reduce the risk of phlebitis and/or pulmonary embolism.

 

Symptoms

Symptoms

 

The cancer of the right colonist can develop for one long period of time without no sign/symptom appearing. When the symptoms appear, they are often vague and can be confused with those of more current disorders. It is important to consult a doctor.

  • Symptoms cancer right colonist

  • méléna or of the rectorragies? presence of blood on or in the saddles (of very dark color or bright red)

       

    tiredness related to anaemia – usually following the bleedings on the level of the intestine

    weight loss or general state deterioration

      

    diarrhoea, constipation or both, in alternation: saddle unusual (during one prolonged period)

        

    revealing complication of the tumour of the right colonist: 1) obstruction of the bowels or perforation (infectious complication with type of abscess perineoplasic) 2) metastatic liver    

Diagnostic and Therapeutic Pre Assessment

The diagnosis of the cancer of the colon rests on the coloscopy which makes it possible to visualize the tumour, to carry out biopsies and to search

synchronous lesions (of the rectum and left colon)

The therapeutic pre assessment of a cancer of the right colon must comprise research
visceral metastases by a hepatic echography and possibly an abdominal examination scanographic thoraco.

The proportioning of ACE is useful to supervise the evolution after treatment.

Right Colectomy

 

Surgical consultation Colectomie Right

The surgeon digestive explained you holding them and the outcomes of the right colectomy which is necessary in your case
The operational date was scheduled.

    A regulation d’ORAL IMPACT will be delivered to you: to begin 7 days before the intervention. This oral supplementation is a drug the purpose of which is to decrease the operational complications post, by increasing your immunizing defenses. • In the event of laparotomy, a belt of abdominal application will be prescribed to you (think of bringing it the day of the intervention)
